Common European Viper

Ofcource I understand if some kids are poking a snake with a stick, the snake will defend itself, but handling snakes gently will most likely not trigger fear in them. Holding them down, stepping on them and othervise make the snake uncomfertable will ofcource induce a bite that is full of venom.

Oh? I was under the influence that snakes as most animals act on instinct if they are scared for their lives, an instinctive reaction for snakes is to empty the venomsacks something I hardly believe they think about before they do. And the reason I say some bites are drybites is that venom is valuable and cost a lot of energy to produce, so when the snakes reach adult age they have a lot more experience with how much venom they use on different occations. They are analytic and wasting venom when there is no need is just evolutionary stupid. But I might be wrong ofcource :)

Smaller snakes are not worse. Yes, they may give you all their venom and an adult may not. But an adult has much more venom than a younger snake so even when it doesn't give you all of it, you are still getting more than a younger one would give. That is a big myth with snakes. They also don't do dry bites as a warning, they do dry bites when you scare them and they haven't had a chance to get their venom ready. That's why when someone is messing with them and they get bit, it is very rarely a dry bite. The snake has just been sitting there getting it ready to inject into the person.

Yes they are, but not deadly. The smallest are the worst as they empty every drop of venom into you when they bite, after they become adults they learn how to control it and about 1/3 of the bites of an adult is drybites as a warning.

I cannot remember, are they poisonous?
